Guidance and manufacturer’s declaration – electromagnetic immunity
The Infrared Thermometer is intended for use in the electromagnetic environment specified
below. The customer the user of the Infrared Thermometer should assure that it is used in such
environment.

NOTE 1
At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE 2
These guidelines may not apply in all situations. Electromagnetic propagation is
affected by absorption and reflection from structures, objects and people.
Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless)
telephones and land mobile radios, amateur radio, AM and FM radio broadcast and TV
broadcast cannot be predicted theoretically with accuracy. To assess the electromagnetic
environment due to fixed RF transmitters, an electromagnetic site survey should be considered.
If the measured field strength in the location in which the Infrared Thermometer is used
exceeds the applicable RF compliance level above, the Infrared Thermometer should be
observed to verify normal operation. If abnormal performance is observed, additional measures
may be necessary, such as reorienting or relocating the Infrared Thermometer.
